The crazy design and autoplay music reminds me of the various Pokémon fan sites I used to visit back around 2002 when I first got Internet at home.
My oh my how web design has changed dramatically over the past 14+ years since I first started using the Internet regularly.
Additionally, the card images on the Cards page coming in with a reverse "dissolve" is a bit of a throwback to when dial-up connections were the norm for household Internet access. (I ought to know since I was on dial-up at home for a whopping 11 years.)
